Abstract
The invention relates to a drying device, in particular to a spray dryer which is used for drying slurry or molding powder. The spray dryer comprises a tower body, an air supply part, a feeding part and a collection part, wherein the air supply part comprises an air feeder and a high-power electric heater. In the spray dryer, a steam heater arranged in the existing heater is omitted, and the high-power electric heater is adopted, so that the heating effect is not influenced by the unstable air pressure of a steam source in the heating process, the heating speed and the evaporation efficiency are improved, the product can be evaporated according to the design requirement, and the purity and the water content of the product can be guaranteed.
Description
Technical field
The present invention relates to a kind of drying equipment, particularly a kind of spray dryer that is used for to slurry drying or powder moulding.
Background technology
Spray dryer mainly is used for to slurry drying or powder moulding.Existing spray dryer structure is as shown in Figure 1, is made up of tower body 1, air-supply part 2, feeding part 3 and collection part 4.Wherein, the tower body top is equipped with hot-air distributor and atomizer, and stretch out under hot-air distributor the atomizer lower end.The air-supply part contains pressure fan 2-1 and heater.Heater contains steam heater 5 and electric heater 2-2, and the steam inlet 5-1 of steam heater 5 connects vapour source, and the outlet of steam heater 5 is connected with the import of electric heater 2-2.When adopting this spray dryer that rare earth oxide is carried out drying,, when vapor pressure is unstable, influence heats because steam heating time is long; Thereby cause that product can not evaporate by designing requirement, drying; The water content of product is high, glutinous easily bucket wall, and yield is low.Adopt steam heater in addition, because vapours is to the erosion of electric heater, the service life of electric heater is influenced, and has little metal impurity in the use and sneak in the material in the tower body, influences product gas purity.
Summary of the invention
The technical problem that the present invention will solve is: when solving existing spray dryer rare earth oxide being carried out drying, because steam heating time is long, when the vapor pressure instability, influence heats; Thereby cause product not evaporate by designing requirement, the water content of product is high, and purity is undesirable; Glutinous easily bucket wall; The technical problem that yield is low, the present invention provides a kind of spray dryer, and it adopts the large power, electrically heater; Improve firing rate and evaporation efficiency, guaranteed product gas purity and water content value.
The technical solution adopted for the present invention to solve the technical problems is: a kind of spray dryer, and comprise tower body, air-supply part, feeding part and collect part, the air-supply part contains pressure fan and heater, and heater is an electric heater.
Further, for reaching desirable heats, the titanium alloy electrically heated rod that it is 63KW that described electric heater has 21 power.
The invention has the beneficial effects as follows: spray dryer of the present invention; Removed the steam heater in the existing heater; Adopt the large power, electrically heater, heating process can not influence heats because of the air pressure of vapour source is unstable, has improved firing rate and evaporation efficiency; Product can be evaporated by designing requirement, guaranteed product gas purity and water content value.
Description of drawings
Below in conjunction with accompanying drawing and embodiment the present invention is described further.
Fig. 1 is the structural representation of existing spray dryer.
Fig. 2 is the structural representation of the specific embodiment of spray dryer of the present invention.
Among the figure: 1. tower body, 2. air-supply part, 3. feeding part, the 2-1. pressure fan, the 2-2. electric heater, the 2-2-1. electrically heated rod is 4. collected part, 5. steam heater, 5-1. steam inlet.
The specific embodiment
The specific embodiment of spray dryer of the present invention as shown in Figure 2; Comprise tower body 1, air-supply part 2, feeding part 3 and collect part 4; Air-supply part 2 contains pressure fan 2-1 and heater; Heater is electric heater 2-2, the titanium alloy electrically heated rod 2-2-1 that it is 63KW that electric heater 2-2 has 21 power.
